    Description

    MKS-UM is a full-range radiation survey device in the field environment, which measures alpha, beta, gamma and X-ray radiation. The gamma radiation dose rate is measured from the background to emergency levels. High protection rating and a hard shell allow using the device in harsh climatic and dusty conditions.
